Off to see Dr Kogelnik next month - any tests definitely to ask for?

Am travelling from the UK and am booked in for August 28th, very excited. I am sure Dr Kogelnik will do a full work up on me, but having not had any specific ME/CFS testing before, are there any labs that I should definitely been asking for? Maybe if any of his current patients could give a run down of what blood tests he offers, that would be amazing as well Cheers y'all, Rob.
